    Abstract: In this study Polyvinyl alcohol (PVA) and (3, 5, 10%)wt microcrystalline cellulose (MCC) were prepared using a solution-casting method. The films that were produced characterized with Fourier Transform Infrared Spectrometry, Differential Scanning Calorimetric, Tensile test, and Barrier properties. The results from FTIR shows that PVA and MCC were c... Show More

    Abstract: This "Paper" presents a comparison of the results obtained by means of the Finite Elementary Lines (EEL) approach to those obtained by other authors in the characterization of periodic microstrip structures on the localization, the width at - 20 dB and the depth of the rejection band. Designers of stop-band or pass-band filters find in this approac... Show More
